我最近想react-native用相机创建一个应用程序并开始使用，react-native-camera所以我这样做了：

$ react-native init testApp2
$ npm install --save react-native-camera
$ react-native link react-native-camera
$ react-native run-android

在最后一行之后，我得到了奇怪的输出（如下）（我的电脑上安装了 Android Studio，当我去构建 apk 时，Android Studio 会创建确切的错误）

Make sure you have an Android emulator running or a device connected and have
set up your Android development environment:

我已经尝试了所有可能的方式来使用 Android Studio 来修复这个错误，但我真的很累，不知道下一步该做什么。:\

这是我的package.json：

{
  "name": "testApp2",
  "version": "0.0.1",
  "private": true,
  "scripts": {
    "start": "node node_modules/react-native/local-cli/cli.js start",
    "test": "jest"
  },
  "dependencies": {
    "react": "16.3.1",
    "react-native": "0.55.4",
    "react-native-camera": "^1.1.3"
  },
  "devDependencies": {
    "babel-jest": "22.4.4",
    "babel-preset-react-native": "4.0.0",
    "jest": "22.4.4",
    "react-test-renderer": "16.3.1"
  },
  "jest": {
    "preset": "react-native"
  }
}

如果你知道这有什么问题，请告诉我，我开始变得非常疯狂......

因为我不知道如何把我所有的代码放在这里，所以我只是把它上传到了 GitHub，这里是它的链接。

尝试启用 multiDex

在app/build.gradle 中：

android {
    defaultConfig {
       multiDexEnabled true
    }
}
